Description

Technical Field

[0001] The present invention relates to the technical field of fire extinguishing bombs, and particularly to a fire extinguishing bomb aiming device and a using method thereof. Background Technique

[0002] As an important equipment in modern fire fighting operations, portable fire extinguishing launchers play a key role in complex scenarios such as forest fires and chemical plant rescues. However, during actual use, the optical sights of these launchers are extremely vulnerable to the attachment of pollutants such as tar particles generated by the explosion and dispersion of fire extinguishing agents, high-temperature soot, and sand and gravel flying on-site. These pollutants not only rapidly reduce the light transmittance of the lens but also cause serious blurring of the aiming line of sight.

[0003] Test data shows that after continuous firing 3 - 5 times, the amount of pollutants attached to the surface of the sight can reach 30 - 50 mg / cm 2 , resulting in the light transmittance dropping below 60%, significantly affecting the aiming accuracy. Especially in a fire scene environment with low visibility, the contaminated sight may cause a ballistic deviation of more than 10 meters, seriously affecting the fire extinguishing efficiency.

[0004] Currently, common solutions mainly rely on manual cleaning or electric cleaning modules, but both have obvious defects. Manual wiping not only requires interrupting the fire extinguishing operation, is difficult to operate in harsh environments such as high temperature and thick smoke, but also has the risk of secondary pollution. Although the electric cleaning module can achieve automated operation, it is limited by battery life and reliability issues at extreme temperatures, and has a high failure rate in high-temperature, high-humidity, or dusty environments in the fire scene. Summary of the Invention

[0005] The present invention aims to provide a fire extinguishing bomb aiming device and a using method thereof to solve the problems raised in the above background technique. This solution innovatively integrates a self-cleaning component and a driving component outside the launch tube, and cleverly utilizes the recoil force generated by each fire extinguishing bomb launch to automatically trigger cleaning. The lens of the sight is wiped by a cleaning block, avoiding the interruption of fire extinguishing caused by manual wiping, ensuring the continuous combat ability of the user. At the same time, the overall self-cleaning component and driving component adopt a pure mechanical structure design, without the need for batteries or motors, and can work stably in extreme environments such as high temperature, low temperature, humidity, and dust.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A fire extinguishing bomb aiming device includes a launching tube, a sight, a self-cleaning component and a driving component. An installation block is connected to the outer end of the launching tube. Both the launching tube and the installation block are cylindrical in shape. A base is connected to the outer end of the installation block. The sight is detachably connected to the base and is inclined with respect to the launching tube. The self-cleaning component includes a connecting block which is connected to the outer end of the installation block. An arc-shaped rod is slidably connected inside the connecting block. The arc of the arc-shaped rod matches the shape of the installation block and is coaxially arranged with the installation block. A cleaning block is sleeved on the outer end of the arc-shaped rod on the side close to the sight. The driving component includes a slide rail which is connected to the outer end of the installation block. A pushing block is slidably connected to the slide rail. One end of the pushing block has an inclined surface. The end of the arc-shaped rod away from the sight abuts against the inclined surface of the pushing block.

[0008] Preferably, the objective lens end of the sight and the cleaning block are at the same circumferential position.

[0009] Preferably, the self-cleaning component further includes a sleeve which is connected to the outer end of the installation block and is set in a bent shape matching the arc-shaped rod. The cleaning block is arranged in the inner cavity of the sleeve and matches the shape of the inner cavity of the sleeve.

[0010] Preferably, a baffle is connected to the outer end of the arc-shaped rod. The baffle is arranged in the inner cavity of the sleeve and abuts against the end of the cleaning block away from the sight.

[0011] Preferably, a limiting block is detachably connected to the end of the arc-shaped rod close to the sight. The limiting block abuts against the cleaning block, and the diameter of the limiting block is greater than that of the arc-shaped rod and less than that of the cleaning block.

[0012] Preferably, a second spring is arranged inside the slide rail. The two ends of the second spring are respectively connected to the slide rail and the pushing block. A first spring is arranged on one side of the connecting block. The two ends of the first spring are respectively connected to the connecting block and the arc-shaped rod.

[0013] Preferably, the slide rail and the launching tube are arranged in parallel.

[0014] A using method of a fire extinguishing bomb aiming device includes the following steps:

[0015] S1: The user first installs the sight on the base, then installs the fire extinguishing bomb in the inner cavity of the launching tube, then carries the launching tube on the shoulder, aims at the fire source position by using the sight, and then launches the fire extinguishing bomb;

[0016] S2: The recoil generated by the launch of the fire extinguishing bomb forces the launching tube to move backward. The pushing block slides along the surface of the slide rail towards the launch end of the launching tube under the action of inertia and stretches the second spring;

[0017] S3: During the sliding process of the pushing block, its inclined surface squeezes the arc-shaped rod and pushes the arc-shaped rod to slide inside the inner end of the connecting block. Then, the arc-shaped rod drives the cleaning block to slide out of the inner cavity of the sleeve. During the sliding-out process of the cleaning block, the air in the inner cavity of the sleeve is extruded, and the extruded air blows away the dust adhering to the objective lens end of the aiming mirror. Subsequently, the cleaning block wipes the surface of the objective lens end of the aiming mirror.

[0018] S4: During the movement of the arc-shaped rod, the first spring is stretched. After the cleaning block wipes the aiming mirror, the pushing block and the arc-shaped rod are reset successively under the elastic force of the second spring and the first spring, preparing for the cleaning work after the next launch. The beneficial effects of this technical solution compared with the prior art are as follows:

[0019] This solution innovatively integrates a self-cleaning component and a driving component outside the launch tube, and cleverly utilizes the recoil force of each fire extinguishing bomb launch to automatically trigger cleaning. The lens of the aiming mirror is wiped by the cleaning block, avoiding the interruption of fire extinguishing caused by manual wiping, ensuring the continuous combat ability of the user. At the same time, the self-cleaning component and the driving component as a whole are designed with a pure mechanical structure, without the need for a battery or a motor, and can work stably in extreme environments such as high temperature, low temperature, humidity, and dust.

Detailed Embodiments

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments:

[0028] As Figures 1-6 shown, a fire extinguishing bomb aiming device includes a launching tube 1, a sighting scope 3, a self-cleaning component 4 and a driving component 5. An installation block 2 is connected to the outer end of the launching tube 1. Both the launching tube 1 and the installation block 2 are set in a cylindrical shape. A base 6 is connected to the outer end of the installation block 2. The sighting scope 3 is detachably connected to the base 6 and is inclined with respect to the launching tube 1. The self-cleaning component 4 includes a connecting block 46. The connecting block 46 is connected to the outer end of the installation block 2. An arc-shaped rod 41 is slidably connected inside the connecting block 46. The radian of the arc-shaped rod 41 matches the shape of the installation block 2 and is coaxially arranged with the installation block 2. A cleaning block 43 is sleeved on the outer end of the arc-shaped rod 41 on the side close to the sighting scope 3. The driving component 5 includes a slide rail 51. The slide rail 51 is connected to the outer end of the installation block 2. A pushing block 52 is slidably connected on the slide rail 51. One end of the pushing block 52 is provided with an inclined surface. The end of the arc-shaped rod 41 away from the sighting scope 3 abuts against the inclined surface of the pushing block 52. The objective lens end of the sighting scope 3 and the cleaning block 43 are at the same circumferential position.

[0029] Portable fire extinguishing launchers, as important equipment in modern fire fighting operations, play a crucial role in complex scenarios such as forest fires and chemical plant rescues. However, during actual use, their optical sighting scopes are extremely vulnerable to the attachment of pollutants such as tar particles generated by the explosion and dispersion of fire extinguishing agents, high-temperature soot, and sand and gravel flying on-site. These pollutants not only rapidly reduce the light transmittance of the lens but also cause serious blurring of the aiming line of sight. Currently, common solutions mainly rely on manual cleaning or electric cleaning modules, but both have obvious defects: 1. Manual wiping not only requires interrupting the fire extinguishing operation, is difficult to operate in harsh environments such as high temperature and thick smoke, but also has the risk of secondary pollution. 2. Although the electric cleaning module can achieve automated operation, it is limited by battery life and reliability issues at extreme temperatures, and has a high failure rate in high-temperature, high-humidity or dusty environments at the fire scene.

[0030] In this solution, the launcher tube 1 and the sight 3 refer to the SLM80 fire extinguishing launcher and its supporting sighting device. The SLM80 fire extinguishing launcher is a portable fire-fighting equipment mainly used for quickly extinguishing incipient fires and emergency rescue in special scenarios. Its total weight is about 8 - 10 kg, which can be carried and operated by a single soldier. It fires special fire extinguishing bombs with a range of 80 - 120 meters. It adopts a shoulder-mounted design with a buffer mechanism. The sight of the SLM80 fire extinguishing launcher and the launcher tube adopt a relatively inclined design, keeping the shooter's head upright and avoiding neck fatigue caused by long-term bending. Actual measurements show that compared with a straight-tube sight, the inclined design can reduce the cervical spine load by 70%. This equipment effectively solves the problem that traditional fire-fighting equipment is difficult to approach dangerous fire sources by delivering the fire extinguishing agent to the core area of the fire source and is currently widely used in the fire-fighting force and industrial safety and security fields.

[0031] In this solution, to protect the sight 3, when not in use, the sight 3 is separated from the launcher tube 1 for storage. During the fire-fighting operation, the user first installs the sight 3 on the base 6. The installation method can be snap connection. Then, the fire extinguishing bomb is installed in the inner cavity of the launcher tube 1. Subsequently, the launcher tube 1 is carried on the shoulder, and the fire source position is aimed at using the sight 3. Then, the fire extinguishing bomb is launched. The recoil force generated by the launch of the fire extinguishing bomb forces the launcher tube 1 to move backward. The pushing block 52 slides along the surface of the slide rail 51 towards the launch end of the launcher tube 1 under the action of inertia. During the sliding process of the pushing block 52, its inclined surface squeezes the arc-shaped rod 41 and pushes the arc-shaped rod 41 to slide inside the inner end of the connecting block 46. Furthermore, the arc-shaped rod 41 drives the cleaning block 43 to move and wipe the surface of the objective lens end of the sight 3, removing pollutants such as tar and dust on the lens. The cleaning block 43 can be set as a flexible cleaning material with strong adsorption ability such as sponge. With this setting, the recoil force of each fire extinguishing bomb launch is cleverly utilized to automatically trigger cleaning, avoiding the interruption of fire extinguishing caused by manual wiping and ensuring the continuous combat ability of the user. At the same time, the device adopts a pure mechanical structure design, without the need for a battery or a motor, and can work stably in extreme environments such as high temperature, low temperature, humidity, and dust.

[0032] The self-cleaning component 4 further includes a sleeve 42. The sleeve 42 is connected to the outer end of the mounting block 2 and is set in a curved shape matching the arc-shaped rod 41. The cleaning block 43 is arranged in the inner cavity of the sleeve 42 and matches the shape of the inner cavity of the sleeve 42.

[0033] In this solution, during the movement of the cleaning block 43, it will be extruded from the inside of the sleeve 42. The cleaning block 43 is at a certain distance from the opening of the cleaning block 43 and the sight 3. Therefore, when the cleaning block 43 slides out of the inner cavity of the sleeve 42, the air inside the sleeve 42 will be extruded. The air is used to first blow away some of the dust on the lens of the sight 3, further improving the cleaning effect. At the same time, the setting of the sleeve 42 can wrap the cleaning block 43 when it is not in use, preventing its surface from being contaminated with dust too quickly and reducing the cleaning effect.

[0034] The outer end of the arc-shaped rod 41 is connected with a baffle 44. The baffle 44 is arranged in the inner cavity of the sleeve 42 and abuts against one end of the cleaning block 43 away from the aiming mirror 3.

[0035] In this solution, the cleaning block 43 is sleeved on the outer end of the arc-shaped rod 41, making it easy to install and disassemble. It can be replaced after each use to maintain its best cleaning effect. The baffle 44 can limit the position of the cleaning block 43 to ensure that it is located at the end of the arc-shaped rod 41.

[0036] One end of the arc-shaped rod 41 close to the aiming mirror 3 is detachably connected with a limit block 45. The limit block 45 abuts against the cleaning block 43, and the diameter of the limit block 45 is larger than that of the arc-shaped rod 41 and smaller than that of the cleaning block 43.

[0037] In this solution, the connection relationship between the limit block 45 and the arc-shaped rod 41 can adopt threaded connection. The limit block 45 plays a fixing role on the cleaning block 43. By abutting against one end of the cleaning block 43, it prevents the cleaning block 43 from falling off the end of the arc-shaped rod 41. At the same time, its size design can avoid its contact with the lens of the aiming mirror 3 and prevent damage to the aiming mirror 3.

[0038] A second spring 53 is arranged inside the slide rail 51. The two ends of the second spring 53 are respectively connected with the slide rail 51 and the pushing block 52. One side of the connecting block 46 is provided with a first spring 47. The two ends of the first spring 47 are respectively connected with the connecting block 46 and the arc-shaped rod 41.

[0039] In this solution, when the pushing block 52 moves, it will stretch the second spring 53. When the arc-shaped rod 41 moves, it will stretch the first spring 47. Thus, after the cleaning block 43 wipes the aiming mirror 3, the pushing block 52 and the arc-shaped rod 41 will be reset successively under the elastic force of the second spring 53 and the first spring 47 to prepare for the cleaning work after the next launch.

[0040] The slide rail 51 and the launch tube 1 are arranged in parallel.

[0041] In this solution, the parallel arrangement of the slide rail 51 and the launch tube 1 can make the recoil force generated by the launch tube 1 more effectively transmitted to the pushing block 52, prompting it to move a longer distance on the slide rail 51, so as to ensure that the cleaning block 43 can complete the wiping of the aiming mirror 3.

[0042] A using method of a fire extinguishing bomb aiming device includes the following steps:

[0043] S1: The user first installs the aiming mirror 3 on the base 6, then installs the fire extinguishing bomb in the inner cavity of the launch tube 1, then carries the launch tube 1 on the shoulder, aims at the fire source position by using the aiming mirror 3, and then launches the fire extinguishing bomb;

[0044] S2: The recoil generated by the launch of the fire extinguishing bomb forces the launch tube 1 to move backward. Under the action of inertia, the pushing block 52 slides along the surface of the slide rail 51 towards the launch end of the launch tube 1, and stretches the second spring 53.

[0045] S3: During the sliding process of the pushing block 52, its inclined surface squeezes the arc-shaped rod 41 and pushes the arc-shaped rod 41 to slide inside the inner end of the connecting block 46. Furthermore, the arc-shaped rod 41 drives the cleaning block 43 to slide out of the inner cavity of the sleeve 42. When the cleaning block 43 slides out, the air in the inner cavity of the sleeve 42 is squeezed out. The squeezed air blows away the dust adhering to the objective lens end of the aiming mirror 3. Subsequently, the cleaning block 43 wipes the surface of the objective lens end of the aiming mirror 3.

[0046] S4: During the movement of the arc-shaped rod 41, the first spring 47 is stretched. After the cleaning block 43 wipes the aiming mirror 3, the pushing block 52 and the arc-shaped rod 41 are reset successively under the elastic force of the second spring 53 and the first spring 47, preparing for the cleaning work after the next launch.

[0047] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics known to the public are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
